PAVEMENT FOR STABLES.

SPECIFICATION forming part of Letters Patent No. 458,'788, datedSeptember 1, 1891.

Application filed September ZO, 1890, Serial No. 365.689. (Ne model.)

To aZZ whom it may cancer/t:

Be it known that I, JOHANN J UNGBLUTH, of Cologne, in the Kingdom ofPrussa and German Empire, have invented a new and useful Pavenent forStables, ot' which the following is a specification, reference being hadtherein to the accompanying drawings.

The invention hereinatter described relates to a composition or concretefiooring for' stables, public and other baths, slaughterhouses, and thelike, and has for its object to fulfill all the conditions which may beexpected' from such fiooring. These condition are that the fion'ingshould be firm, clean, and dry; that it should allow sewer or drainwater to run off readily, which treading or walking thereon and Withregard to stables the com-1 fortable lying down of animals should not beprevented or interfered with.

The salient feature' of the composition' floor-ing hereinafter describedis the use of. sloping or drain channels or gut-ters to receve therunning-off Water or liquid sewage, these channels being wide below andnarrow at the top, while in some cases they' have such a form that evenwhen the material of the floor-ing adheres as tightly as pos-z siblethereto only a small opening or slot of this channel is visible. Thisopening is protected by special means, so as not to become closed 01'clogged; These outlet Channels, drains, or gutters are, according to themethod hereinafter explaiued, formed in the fiooring or built therein insuch a manner that they increase uniformly on the sloping side and leadto the main Sewer. These Channels are further opened in their uppernostpart, so that branch conduits of a corresponding water-snpply can beconveyed thereto for the purpose of fiushing the channels. The latterare further provided on their inner sides with projecting edges in sucha manner that the drain-Water or liqnid sewage can easily drip throughand that the same is prevcnted from Sinking in the fiooring.

A fiooring has already been described in the English Blue Book No.3,713, in which, it is true, also outlet-channels were used. Theseoutlet-channels, however, were narrow at the top and widened below inthe form of a cone, in cousequenee of which Construction the liquidadheres to the walls and by evaporating infects the air. This is a greatdrawback, which is entirely avoided by the present in- Vention by givingthe channels a form as to let the liquid only drop down on bottomswithout touching the walls at all. The bottom may at any time be fiushedand kept clean. As already pointed out, the projecting edges on theinner sides of the channels have such an excellent salubrious effect notobtained yet by the fioorings known hitherto.

The above-mentioned outlet or dr'ain-channels are built with thematerial of the flooring, which consists for this purpose of two stronglayers-a lower and an upper layerwhich are prevented from mo-vingrelatively to one another by means of peculiar projecting edges andcorresponding openings or grooves.

The object of the invention is illustrated in the accompanying drawings,in which- Figure I shows a floorng in upper as well as a lower View,partly with the upper plates taken off. Fg. II is a eutting or sectionin the direction of the cutting-line 9600 of Fig. I. Fig. III is a sideView of Fig. I. Fig. IV is a perspective View of the flooring. Fig. V isa cutting through line .e 2' of Fig. IV.

In the ooring the upper Stones a andlower stones h are of peculiar fornand are peculiarly connected with one another in such a manner as toform drain conduits or channels F, which have the required depth and arewider at the bottom than at the top. The Stones h of the lower layerhave a suitable shape and are made of cement, slag sand, or the like.They may, however, be formed of burnt clay. The Stones a of the upperlayer are made of a mass eonsisting, essentially, of sharp sand,powdered basalt, lava slags, Niedermenning stone or cement mixed insuitable proportions, such mass being castin suitable molds after havingbeen previously noistened with a small quantity of water having atemperature of about 12 centigrade, while its surface is eovered with anupper layer about one to two centimeters thick. The substance tormingthis top or covering layer contains besides the above-nentionedmaterials which are incorporated therewith, a suitable addition of ironturnings or shavngs and impure sugar. This addition renders the uppersurface of the stones particularly hard and eapable of withstanding theaction of water and liquid sewage after the same has been dried in theopen air. The stones of the lower layer can likewise be provided ontheir surface with a similar protecting-layer. The stones h of the lowerlayer have for their object to form one of the arches of thedrai-conduits, as well as to hold the upper stones in theircorresponding position, and are for this purpose provided withprotuberances in the longitudinal direction of the channel F. Thedrainchannels F are formed with a suitable inclination for water andliquid sewage. The lower stoneshare placed over a suitable length and inregular joints in a layer of sand r', the stones being provided at theirends with projections P, fitting in corresponding cavities of the adjacent stones. The lower stones are joined adjacently by means of mortaror asphalt l. The protuberances N and O, arranged on the lower stonesparallel to the drain-channel F, serve as a connection with the upperstones a, which are laid in rows upon a foundation of fine well-strainedsand in the drain-channel F, formed of the lower stones. The upperstones a are of such dimensions that -between each two rows of stones aninterval or opening b is left, through which the water or liquid sewagemay pass into the corresponding drai'n-channels F. From the channel Fthe water runs in a sewer G, arranged in the center of the stable orotherwise. The two abutting sides of the stones a are con nectedtogether by means of cement or asphalt, and thus rendered water-tight.The fiat surface of thelower stones h, toward the drain-channels F, andthe corresponding inclination of the upper stones a, as well as thearrangement owing to which the upper stones a project with their edge y(which is especially characteristical) somewhat beyond the walls of thechannel F formed thereunde',

cause the water or liquid sewage to be con veyed readily within thelat-ter without such liquid being allowed between or above thefoundations.

Suitable branches of a water-supply pipe K lead to the higher portion ofthe drainchannel F and by these means the latter can be fiushed wheneverrequired.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. A composition flooring for stables, public or other baths,slaughter-houses, and the like characterized by the use ofdrain-channels of taperine* section, which are slotted at the top in alongitudinal direction, are provided laterally with projections y forthe clean and ready drainage of the water, and are so formed by the saidflooring that the latter does not slope, as hitherto practiced, in thelongitudinal direction of the drain-channels, but it is inclinedlaterally toward each pair of drain-channels, substantially asdescribed.

2. In composition flooring of the kind set forth, the drain-channelsformed of lower stones h, which are provided at their upper edges withinclosed protuberances N O and with inner cavities running in alongitudinal direction, and of upper stones a, laid thereon andconnected therewith by means of a layer of sand, the latter stones beingheld in place by the former, and forming in the direction of thedrain-channels F of the lower stones small intervals or passages,allowing the water or liquid sewage to be readily d'ained off,substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
